Our in-house design capability allows us to provide cost-effective and unique temporary access platforms and work trestles for our equipment and others’. We’ve constructed platforms and trestles for large cranes, drill rigs, large excavators, concrete pumps, elaborate scaffolding and staging elements, and temporary bridge-launching equipment. As with most of the work we perform, each structure is tailored to meet the needs of the customer, the pieces of equipment utilizing the structure, and soil and rock conditions.
